Season 3 'The Sing Off' Winners Hit Orlando

Pentatonix may have gotten a healthy boost to fame from NBC's “The Sing Off,” but their blow out concert in Orlando proves that it wasn't just luck that saw the band to victory. Singing popular hits like “Somebody I used to Know” and “Aha,” the band delivered everything their fans could ask for and more.

Pentatonix performed at the House of Blues Orlando in Downtown Disney on Nov. 28, 2012, to an almost, if not, sold out crowd. The line was longer than usual with faithful fans waiting to get inside and out of the chilly weather.

One year ago to the date of their performance at the No. 1 rated club (Billboard) in North America they had won Season 3 of NBC's "The Sing Off." Not only did the future of Pentatonix change that night but the music industry was about to see a whole new genre of a mainstream a cappella rock and pop.
